About this study

Healthy volunteers will participate in a single session study with a crossover design.

During the study healthy participants will be randomized to either receive a injection of hypertonic saline (painful injection) or isotonic saline (control injection) in a neck muscle.

Head repositioning accuracy will be assessed with and without performing a cognitive task.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Healthy men and women aged 18-50 years
  • Right handed
  • Able to speak, read and understand Danish or English
  • Normal pain free neck and shoulder range of motion

Exclusion criteria

  • Pain from the neck or shoulder area
  • Prior surgery in neck or shoulder
  • Pregnancy
  • Drug addiction defined as the use of cannabis, opioids or other drugs
  • Self reported neurologic, musculoskeletal or mental illnesses

Treatment and study plan

Injection of hypertonic saline

Drug

Painful condition: Participants will be injected in a neck muscle with 0.5ml of hypertonic saline (5.8%)

Other names: Hypertonic saline (5.8%)

Injection of Isotonic saline

Drug

Control condition: Participants will be injected in a neck muscle with 0.5ml isotonic saline (0.9%)

Other names: Isotonic saline (0.9%)

Primary outcomes

  1. Change in head repositioning accuracy

    Time frame: Within session (session lasts approximately 2 hours)

    Participants will be blindfolded and asked asked to, from a neutral position, to move the head into full range of motion before returning to to a neutral position again. The difference between the start and end position will be used as an estimate of head repositioning error.

Secondary outcomes

  1. Change in perceived pain

    Time frame: Within session (session lasts approximately 2 hours)

    Pain will be scored using a scale from 0-10 with 0 being no pain and 10 being worst imaginable pain, by drawing on body charts and choosing words from the McGill Pain Questionnaire.

  2. Change in perceived performance of head repositioning accuracy test

    Time frame: Within session (session lasts approximately 2 hours)

    Likert scores of the perceived difficultness (0=no problems, 1=minimally difficult, 2=somewhat difficult, 3=fairly difficult, 4= very difficult, 5=unable to perform)
